Two real gaps found after testing the live standby platform:
1. modules/kubernetes.py's in-cluster client (load_incluster_config())
can only ever work inside the real k8s pod. On the standby it silently
returned K8S_AVAILABLE=False with zero fallback — Cluster, Containers-
via-sites, and any cluster/app health data was just empty on that page,
not erroring, so it was easy to miss. This holds even if the standby
later runs as a pod on a *local* k3s on that server (per plan for the
monitoring migration) — in-cluster config there would only ever see
that local, unrelated cluster, never the main one.
Fixed by adding an SSH+kubectl remote path to list_pods(), list_
deployments(), get_ingress_info(), list_deployments_for_namespace(),
and get_pod_metrics(): when not RUNNING_ON_MAIN_SERVER, each runs
`kubectl <verb> -o json` on the main server over the tunnel
(main-to-vm-tunnel.service) instead of using the python client, parses
the raw (camelCase) JSON directly rather than trying to force it
through the client-library's snake_case object model, and feeds the
same _pod_health/_deploy_health/_age_str helpers either way. The
in-cluster path for the real main-server pod is untouched.
2. get_system_info() called psutil.* unconditionally with no
RUNNING_ON_MAIN_SERVER awareness at all — on the standby it was
silently reporting the VM's OWN cpu/mem/disk/hostname mislabeled as
"system info" (hostname field literally showed the VM's hostname).
Added _get_main_server_system_info_remote(): SSHes to the main server
and gathers the same stats via vmstat/free/df/procfs (the main
server's bare host has no psutil — that's only in this app's own
container image — so this avoids depending on it being present
remotely).
Verified end-to-end on the live standby: /api/system now reports the
real main server's hostname/cpu/mem/disk/uptime; /api/cluster reports
real counts (19 pods, 16/16 deployments healthy, 3 degraded, plus live
per-pod metrics via the metrics-server raw API); /api/sites shows real
per-app container/role status. All previously silently empty.
The standby's "SSH to main server for containers/stats/system info"
fallback (RUNNING_ON_MAIN_SERVER=False path) was wired in code across
backups.py/users.py/commands.py/app.py but never actually worked:
outbound SSH from the VM is blocked by its own firewall (deliberate
hardening — ufw DENY OUT on 22/tcp and 2222/tcp, left untouched), and
separately the VM's contabo-key was never added to the main server's
authorized_keys in the first place.
Fixed via a persistent reverse tunnel instead of opening the VM's
firewall: main-to-vm-tunnel.service (systemd, auto-restart) runs on the
main server and keeps `ssh -R 2224:localhost:22` open to the VM, so the
VM can reach the main server's SSH via localhost:2224 without ever
needing outbound access itself. Added the standby's public key to the
main server's authorized_keys (chattr +i-locked — unlocked, appended,
re-locked immediately).
config.py (gitignored, not in this commit — edited live on both servers
directly) gets new MAIN_SERVER_SSH_HOST/PORT ("localhost"/"2224"), kept
deliberately separate from the existing MAIN_SERVER_IP (which stays the
real IP and is still used for on-page display in several templates —
overloading it for the tunnel target would have silently changed what's
shown in the UI). All four call sites switched from
MAIN_SERVER_IP/MAIN_SERVER_PORT to the new pair. Also fixed a pre-existing
bug in commands.py's run_command(): its SSH fallback had no -i key at all,
so it could never have authenticated even with the tunnel in place.
Verified end-to-end on the live standby: run_command(), backups.py's and
users.py's _ssh_main() all confirmed to actually execute on the real main
server (hostname/whoami/backup count all matched), not erroring or
silently no-op'ing.
backup-k8s-apps.sh now tracks step-level failures (manifests, secret,
db_dump, pvc_data) into an ERRORS array during the per-app loop, and
writes a .meta.json sidecar alongside each archive once all 3 storage
tiers are known - apps included, final size, the error list, and
per-tier ok/failed/skipped status. Sidecar is mirrored to VM/R2 the
same best-effort way the .sha256 sidecar already is, and cleaned up
by both local and R2 retention pruning plus manual delete.
modules/backups.py reads these sidecars (never decompresses the
archive) to compute a status per backup at list-render time:
- red: any recorded error, or any tier status starting with "failed"
- yellow: no errors, but size deviates >40% from the rolling average
of the last 5 backups sharing the same app-combination (apps_key)
- green: no errors, size within range (or first backup of its
app-combination - nothing to compare against yet)
- unknown: no sidecar at all (legacy myapps-backup-* archives, or
any k8s backup made before this shipped) - no backfill attempted,
old runs never recorded step-level failures to reconstruct from
/backups route now passes get_local_backups_with_status()/
get_vm_backups_with_status() instead of the plain filename lists
(get_local_backups()/get_vm_backups() themselves are untouched -
/restore and /api/backups still use the plain versions, they don't
need the dot). Template renders a colored dot next to each entry with
a tooltip showing apps/size.
Verified: real n8n backup produces a correct sidecar synced to all 3
tiers; JSON-writer argv parsing and the red/yellow/green/unknown
decision logic each checked against synthetic cases; full Jinja render
checked against real local + VM data pulled from the live pod.

Two separate bugs found while testing the Audit/Details UI against a
real k8s-format backup (myapps-k8s-backup-*):
1. Format-hardcoded checks. audit_backup()'s Internal Structure and
Volume Count checks assumed the legacy Docker-era archive layout
(volumes/*.tar.gz, compose-files/) and would fail every k8s-format
backup (per-app dirs with manifests.yaml/db-dump.sql.gz/pvc-data.tar.gz)
even when it's perfectly healthy - same root cause as the
myapps-backup-*/myapps-k8s-backup-* prefix bug fixed earlier, just in
the audit checks instead of the listing/delete glob. cloud_backup.py's
r2_audit_backup() had the identical unpatched filename regex, and
app.py's /api/backups/details route had its own, which outright
400'd any k8s-format filename before even looking at it.
2. A bigger, separate bug this surfaced: get_local_backups(),
get_vm_backups(), and _resolve_archive_path() all branch on
RUNNING_ON_MAIN_SERVER to decide between direct filesystem access and
SSH-to-self - and from inside the management-platform pod that flag's
hostname check can be wrong for the pod's own ephemeral hostname
depending on how it's evaluated, sending these down the SSH branch
using a topology (separate warm-standby-on-the-VM SSH path) that
doesn't apply to a pod that already has /root hostPath-mounted in.
Fixed by trying direct filesystem access first wherever the archive
would already be locally reachable, falling back to the existing SSH
paths otherwise - this preserves the original warm-standby-on-VM
failover design (a real second deployment of this platform on the VM
host, kept reachable via SSH when the main server is down) completely
unchanged; it only adds the fast local path for the case where the
caller already has direct filesystem access.
Verified against both a real k8s-format backup (odoo, single-app) and a
real legacy-format backup on disk - both audit correctly now, with
format-appropriate checks and labels.

modules/sites.py was still a fully Docker-era hardcoded registry:
container names (odoo-clean-odoo-1, frappe-erpnext, nextcloud-app,
mautic-app, n8n-app) that no longer exist post-migration, checked via
`docker inspect` over SSH, plus hardcoded domain/port fields -
nextcloud and mautic even had domain: None, silently falling back to
dead Docker host-port URLs while their real Ingress domains
(next.cloud.nav.ovh, mautics.nav.ovh) sat unused.
Now sources everything live from the cluster:
- Domain + TLS from the actual Ingress object per app (via the new
get_ingress_info() in modules/kubernetes.py), not a static guess.
Odoo/Nextcloud's Ingress lives in `default` (see prior commit for the
RBAC this needed); n8n/mautic/erpnext's lives in their own namespace.
- App/DB/cache/worker/scheduler status from real Deployment state
(list_deployments_for_namespace(), new in modules/kubernetes.py)
instead of `docker inspect`.
- Health probe now hits the real domain directly from the pod (it has
normal internet egress) instead of SSH-ing back out to the host to
curl a public HTTPS URL, which is what the RUNNING_ON_MAIN_SERVER
branch would have done for a pod whose hostname never matches the
main-server hostname check.
Same API/template contract as before (get_sites_list/get_site_health
return the same field shapes) - templates/pages/sites.html needs no
changes.

api_backup_run and restore_start were still hardcoded to the Docker-era
backup-myapps.sh/restore-myapps.sh, which target Docker volumes that no
longer exist for the 5 apps now running in k3s (n8n, odoo, mautic,
nextcloud, frappe/erpnext) — every backup/restore triggered from the UI
has been silently hollow for these apps since the migration.
- api_backup_run: /root/backup-myapps.sh -> /root/CloudOps/backup/backup-k8s-apps.sh
- restore_start: switched from the old image-relative path (which resolved
to /app/restore-myapps.sh, baked into the Docker image from platform/)
to an absolute /root/CloudOps/backup/restore-k8s-apps.sh path — the new
backup/ folder is a sibling of platform/, not part of the Docker build
context, so it's only reachable via the pod's existing /root hostPath
mount, the same way api_backup_run already reaches its script.
--apps flag shape and the job-log streaming contract are unchanged, so no
frontend/template changes needed for the core flow. modules/backups.py's
three hardcoded myapps-backup-* references (get_local_backups, get_vm_backups
x2, delete_backup's filename regex) now also recognize the new
myapps-k8s-backup-* prefix, so both backup lineages stay visible/manageable
in the UI.
Depends on the previous commit (scoped ServiceAccount + k3s kubectl access
for the pod) to actually function when triggered from the UI.

New modules/kubernetes.py lists pods and deployments across the 8 app
namespaces via the in-cluster management-platform-viewer-sa (read-only,
no secrets/exec/log), with metrics-server usage as a best-effort extra
that degrades silently when unreachable. New /cluster page and
/api/cluster endpoint, nav entry, and templates render pods/deployments
grouped by namespace using the existing card/badge design system.
Additive only — no existing Docker routes or views touched.
